Can't connect to Forza Horizon 4 online

I have checked it, it is not my hardware and driver problem.

This problem will only occur if the xbox app is connected to the Internet.

This problem makes forza horizon 4 no way to play online mode.

If there is really no way to solve it, can I refund the Forza horizon 4 Ultimate Edition?

you can't join online play in forza horizon 4 until you have completed the first 4 seasons and got on the roster and reached level 20

Hello There ! I highly recommend following the troubleshooting steps mentioned on the link below:

We also recommend troubleshooting your network :

You will need an active Gold subscription to be able to play online, aswell as a stable internet connection.

Forza Horizon 4 will automatically join the online lobby if you have a gold subscription.

Thanks for trying Lester, but none of that helped. Still unable to connect to multiplayer in Forza Horizon 3 or Forza Horizon 4 on PC.
